Climate Change: Myth or Reality

Earth's atmosphere is a critical system for life on our planet. Together with the oceans, the atmosphere shapes Earth's climate and weather patterns and makes some regions more habitable than others. Climatic conditions help to shape various ecosystems and habitats around the globe. As the climate changes, species and ecosystems respond by adapting, migrating or reducing their population. Human evolution, in itself, is an outcome of changing climatic scenes. Climate changes naturally, but it is increasingly being thought that human activities are changing this natural variability through making changes in atmospheric chemistry. There are alarmists saying humans have outrun the natural cyclicity, but are also the deniers refuting the change. The theme of the present work- Climate Change: Myth or Reality, is, however, skeptical and is founded on the Aristotelian philosophy that a thought should be entertained without accepting it. There is no doubt that climate is changing. But it has changed in the past as well even in the absence of humans.
